i just found out that i have at least three and quite possibly four to five bristleworms in my tank, which currently has no octo in it but i plan to get one in the next week or so. i have set up a make shift trap for them and i will be purchasing four to five peppermint shrimp (i also have some glass anenomes that i want to get rid of). has anyone had any experience with bristleworms in an octo tank? are they harmful to octos??
